Foundation problems in Texas homes show up as a consistent set of interior and exterior signs, driven by expansive clay swelling and shrinking with moisture. In the Abilene area the soil is Sagerton and Tarrant clay with a plasticity index around 18 or higher, and the 2011 and 2022–2023 droughts each produced a wave of these symptoms across the Big Country. Here is what to look for and what each one means.
Inside the house
- Doors that stick or won’t latch, year-round, especially several on one side. The opening has racked. See sticking doors.
- Diagonal cracks from the corners of doors and windows in drywall or plaster.
- Gaps opening at the top of door and window trim, or crown molding pulling away from the ceiling.
- Floors that slope, dip, or bounce, or a hump you can feel in the center of the house.
- Cabinets and counters separating from the wall.
- Cracked tile or grout in a line across a floor.
Outside the house
- Stair-step cracks in brick or block, following the mortar joints, widening toward the top, usually near a corner.
- A gap between the brick and a window or door frame, or between the brick and the roofline soffit.
- A visible dip in the foundation edge, one corner or side sitting lower than the rest.
- Separation between the slab and the front porch, garage floor, or a patio.
- A leaning chimney or a porch column pulling away.
- Doors and garage doors out of square.
Reading them together
One sign in isolation, a single hairline crack, one sticky door in a humid month, is usually not urgent. The picture to act on is several signs telling the same story: brick cracking on the north side, doors sticking on the north side, and the floor sloping toward the north wall all say the north edge has settled.
Call soon vs monitor
Call soon: wide or offset cracks, a foundation edge clearly lower than the rest, cracks that have grown noticeably in a year, a leaning chimney or porch, a visible gap to the outside, or any exit you cannot open in an emergency.
Monitor and document: seasonal hairline cracks that open and close, a single sticky door, minor trim gaps. Photograph with scale, date them, and get a baseline survey so future change can be measured.
Bottom line
The signs cluster by location and tell a direction, settlement pulls things down, heave pushes them up. When multiple signs point the same way, or anything is wide, offset, or growing, get the free manometer survey. Call (325) 399-3448.
Quick answers
What is usually the first sign of foundation trouble?
For most Abilene homeowners it is a door that starts sticking, or a hairline crack appearing at a door or window corner, often at the end of a dry summer. Exterior stair-step cracks in brick tend to show up a bit later once the movement has progressed.
How fast do foundation problems get worse in Texas?
It varies with the weather. Movement on high-plasticity clay is driven by drought and rain cycles, so a foundation can be relatively stable for a couple of mild years and then move noticeably through a single hot, dry summer like 2011 or 2022-23. Progressive cracks that widen every season should not be left.
Which signs mean I should call right away versus monitor?
Call soon for wide or offset cracks, a foundation edge visibly lower than the rest, a leaning chimney or porch, a gap to the outside, or any door or window you cannot open in an emergency. Monitor and document seasonal hairline cracks and a single sticky door, then get a baseline survey.
